I'm working on a Markdown text editor using a contenteditable and Rangy to easily add links and images. The problem is that rangy.createRange();, an important function in the Rangy library, cancels the ability to undo an action (text added in the contenteditable in my case).
I have browsed the Web to find a solution and I have found UndoManager, but I cannot find information about how to use it and if it has been added in Chrome (I'm working on a Chrome Packaged App so I don't care if Safari does not support it).
If somebody knows something about this piece of HTML5 it would be amazing.
Thanks in advance.
According to this link , none of the current browsers support the UndoManager spec. You can test that in your browser by trying to access document.undoManager which undefined in Chrome
